Be it known that 1, JOHN O.

Gig D I r] Che/5611 01G) United States, and resident of lVestfield, in theicountyot Ha-nipden and State of Massachusettsjhave invented anew and useful Improvement in Slub Catchers of which the. following is a specification.

The object of my invention is to provide a. novel form ot slubcatcher having a yarn clearing hole which will be readily'adjustible for yarns of various sizes; through which the yarninaybeeas-ily and quickly threaded and which will not chat'e nor scrapethe yarn; I l invention comprises-a slub catcher having two .coacting members forming between them a yarn clearing hole. one of the members beinginovable to change the size of the hole and-also ino-viable to open the hole. means vbeingemployed for yieldingly holding the members together. I

My inrention more particularly comprises a structure in which. one of the members has a slot,- the walls ot which form a'portion off the'yain clearing. hole and the other men;- her hasarotativelyadjustable discwith its peripheral surface disposed lengthwise along said slot to form the remaining portion of the hole, said peripheral surface-being graduated ortapered circumferentially so that the size of theyarn clearing hole may be readily changed by a rotative adjustment of the disc; means being employed, suchftfor instance by making-the slot in one of the members inclined for deflecting the yarn as it enters the slub'catcher to require the movement of the other member open the hole for the proper threading of theyarn f Practical embodiments of my invention are represented in ings, in which-f" 7 A I V I Fig.1 represents in top plan a device for guiding, tensioningand clearing yarn with n'iy-invention applied thereto.

- Fig. 10 represents a similar-view, showing thedivergent side walls of the slot as being concave.

Fig. 11 represents a similar view, showing; the graduated peripheral surface of the movable member as comprising a circumferential slot with divergent side walls, to form with the slot in the other member a rectangular hole, as distinguished from the triangular holes shown in the other views.

The bracket as herein COIlS-tlllCtQtlCOlilprises the longitudinal portion 1 terminating at one end in a turned-back portion 2, and at its other end in. upwardly and outwardly inclined ears and et. A loop is formed at one side of the portion 1. of the which loop comprises the lateral branches 5 and 6, connected by the longitudinal branch 7. An arm 8 projects forwardl from the yarn support in the tension device.

A pin 9 uprises from the arm 8, upon which pin is loosely mounted the weighted tension disc 10,, between which disc and the top surface 0? the arm 8 the arn is passed on its way to the slub catche" to be hereinafter described.

The lug 11 projects laterally from the portion 1 of the bracket in the opposite direction from the branch 6 oft-he loop, into which lug is screwed the pivot pin 12 on which a vertically yielding lateral swinging guard 13 is pivoted. The vertically yielding movement of this guard is provided for in the present instance by a recess 14, within which there is located a coil spring 15, interposed between the bottom of the recess and the head of the pin 12. The outer end of this washer guard 13 is provided with 'a portion 16 which projects over the weighted washer 10 and on top of the pin 9 of the tension device when the guard is in its operative position.

'Means are provided for yieldingly holding the guard in its operative position,

bracket,

two coaclting members, one having a slot which means isherein shown as a notch and projection onnection between the guard and the turn'etlback portion 2 bf the braeket; the notch 17 being formed in the. guard-and the projection 18 being formed on the said 7 turned-back portion.

hen the guard is swung back out of its operative position, the Weighted Washer 310 may be readily removed from the pin 9.

The slub catcher let the yarn eempnseswith Walls forming a portion at the; clearing hole, and tlieother with a graduated surface forming the reinaining portion 7 r i V i ofthe said yarn clearing hole.

In the resent instanee themed manner is the branch 5 of the loop hereiiib'efo're' de inclined lugs 3 and tof thebr'aeketotlttvardly and downwardly inclined pii ot with the s'i scribed; which branch is shown as provided 7 with an outwardly and downwardly ineliiied slot 19 across itsupper face, the divergent -xva lls of which slot member of the slab catcher ishereiri shoivn as eoniprisi'ngv tw'o arrned lever 20, pivoted between the upwardly and outward y eer e 5t 21. ne arm of tiis lever ma be provided with a handle 22 for n anipulating the lever. The otherar'rii ofthe lever is provided with a rather/ 13 adjustable disc having its cireuinferentially graduated or tapered peripheral surface 24 disposed iengthwis aiong the ontivatdly andcdorvn r Wardly inclined slot the other ni'eir'riber def edges o'f the disc in Contact ivith the divergent Walls of said slot, to form the'third side of theti'iangular y'arn clearing hole. The disc123 is loosely 1noun'ted on the pivot screw 25 winehpassesan:

ally through the disc into the sa'id'levei, so that the disc 23 will center itself in the slot of the other nieinber, fo ming a pomp ete hole. The means Which Thave shown for locking the discin its rotatively adjusted position is shown as a removabl pin 27 pass ing' through one of a concentric series of holes 26 in the disctinto the hole 28 in the lever 20. l A set screw 29, having its head 30 countersunk in a recess 31 of anuprising lug'GQ, serves to engage the pin 27 to loelejt against uniht'efitiohai removal;

VVhen it is desired to rotatively adjust the disc'j23to change the size of the yar clear- 'ing hole, theset screw 29 is loosened by a 7 special tool; the pin. 27 is then insefted through the proper hole in the disc and into the levee, t e the set; seiexv 29 is then tight .7 together, Whichnieans is herein shot'vn as, a .coil spring 33 extend ng betweenthe bracket and-the lever, To open the yarn clearing ened to lock the parts in their adjusted position. V i 1 V Means areernployed ioryieldi ng'ly holding the eoactihg memb r's ofithe sl'uh-catchet foiiri 't'r'i o sides of tri angular yarn clearinghole. The othet' on an hole to permit the threading or" the yarn, the 'clise may be lifted eutgdf the slot by depressing the the tension of the spring 33.

It will be understood that g t-he rotative Y adjustnientoi the-disc will change thesize of the yarn clearing hole because of the graduated or tapered peripheral surface of the disc, to suit yarns of various sizes; this adjusthientof thejs'i-Ze of the yarn clearing V handle 22 of thelever' 20 against hole being vofa veryline degree, so as to ensurethe best resiilt's'. in clearing theyarn.

It ivill also be seenthat only one clean ing holehiaybe proideathetwq chatting "members of the slu'b yc'atehei' being capable oi 'adjustinentto change the size ofthehole, to suit yarns of varioussiz'es andalso'being capable; :o-i inovernent1to 'open the litile to p'er'mit the threading Of the "yarn.

The reason fei theiprmnslo ofac'nrve'd surtaeeie one at the memberseoa'eting'rvith' the some the other member, is to alloiivthe yarnrto entei' ante-the slhbpateher Without scraping. oi chafihg the yarn as would be the case here a'square surface is used.

When either a thinblade r squint or ree- V tahgular Vbloc'k'is used an edge is *pr'evide'd j r 1 which comes in e'ontaet with the yarn-tn the entering sidefof' the slab hatchet This is void d-in the presentinvention.

The reason-fer negating the yarn, inithe present instance ty' h en ing the slot ut;

Wardly and downwardl is to conipe'lthe I p ev a the yarn through the slab catcher, if the disc the hole for tIiJhr adihg off is not raised to'open tesl6tfer threadiiig the yarn, the yarn Willbe eaught'oi'ftt edged between one sideof the disc and one side wallo'f the sl'ot5 a1id thus cause thejfarn to break. Itjis therefpie abseihteiy necessary to open the yarn elearin'ghole' to properly' thread the arn through "the lab car -her Wound oh'the Winder v I n I Wh ne I have show the yar clearing hale in several'of thefo'rn s as triangular and in another tor n as rectangular in cross "sec before theyarn cian be slubbed, run he non, it is theses; thattheerosfs sheath of the hole he ot'anj 'cles'ir'e shape s ori as-it fills the requirements ofthe ihve hh hrrahgemeht of theseverai Without as? parting from the spirit and scep er in= vention; hence I do not to lamprey It is also evident that venous ehahges may V be resorted to n the construct tin,'forin and j self to thepafticiilar eifithdiiaefits herein i .to bring difirent portions (if said graduated surface within said slot tochange the size also movable toopen the hole.
